Wiring
Pay special attention to the following when wiring:
1. Do not touch R, S, T and U, V, W immediately after the power is off since the capacitance
inside the servo drive can still contain a dangerously large amount of electric charge. Wait
3
until the charging light is off.
2. Separate R, S, T and U, V, W from other wires. The separation should be at least 30 cm
(11.8 inches).
3. For the connection cable for CN2 and CN5, use a metal braided shielded twisted-pair cable
that conforms to UL2464 specifications.
4. When using RS-485, CANopen, DMCNET, or EtherCAT, use the shielded twisted-pair
communication cable to ensure the communication quality.
5. When selecting the wires, refer to Section 3.1.6.
6. Do not use any external capacitor, or it may damage the servo drive.
